I believe that geese move north in the summer and then follow the magnetic
lines during the fall. I have gotten good info from niman and followed up to the fact there is no hard tracking evidence of the migration routes of numerous species of avian, such as the bar headed geese. The migration routes that are imposed apon us is from remote regions of the world. siberia,
tibet, and former russian lands.
The H5N1 virus is being passed by conjugative transfer from commersal bacteria laying on the plasmids gene pods for the allowence of RNA Swapping
for resistance genes.
I wonder if anyone can add or subtract from my last statement, but yes there
has to be avian movement and there has to be outbreaks of human diseases
to account for the movements. B)
